' s. SEGAL WINDOW LOCK FASTENER Filed May 5, 1931 ATTORNEY Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE 3 Claims.

The present invention has general reference to a fastener for maintaining companion window frame members against movement and rattling within the rails or guiding channels of a casing normally containing said members in slideable relation and more particularly the invention aims to provide a construction and arrangement whereby the frame members may be suitably locked with reference to one another in any position namely, either, closed, or open or partly open, although in a broader aspect, the invention comprehends a fastener which may be applied to a wall of a casing supporting one or more window frames for securing either of these against movement or rattling.

A feature of the invention is to provide an improved fastener having a novel clamping element mounted on a supporting member containing a clutch which is responsive to the actuation of said element, if the latter be rotated in one direction concomitantly providing a guard against retraction of the element upon the rotation thereof in an opposite direction.

Another feature of the invention is to provide a manually controlled clutch which if rendered inoperative permits either the clamping member to be adjusted forwardly or rearwardly with respect to its support or withdrawn therefrom. Another aspect of the invention contemplates the provision of a clamping device which releases the clutch on each revolution to permit the device to operate or alternatively is prevented from being operated by the action of the clutch.

Still another feature of the invention is to provide a novel fastener easy to operate and quick to adjust, economical to manufacture and comprises relatively few parts.

The invention will be better understood from the following detailed description of one exemplification, reference being had to the annexed sheet of drawing in which:

Fig. 1 is a plan View of the fastener or window lock shown partly in section, mounted on a window frame casing and secured against a window frame.

Fig. 2 is a view taken along the line 22 of Fig. 1 in the direction of the arrows.

Fig. 3 is a section taken along the line 33 of Fig. 2 in the direction of the arrows showing the clutch in the normal or raised position.

Fig. 4 is a fragmentary sectional view illustrating the clutch depressed to permit retraction of the'clamping element.

Fig. 5 is a perspective view of the window lock fastener shown mounted on the lower forwardly disposed window frame and tightened against the upper rear window frame or sash.

With the embodiment of my invention illustrated in the accompanying drawing, it is desired to lock and fasten the front and rear win- 00 1 bored and countersunk to permit entrance of a securing member 16 for rigidly holding the fastener 12 to a transverse brace as 17 of the front window frame member 11 (Fig. 5) or to one wall of the frame casing 9 (Fig. 1).

The clamp and clutch support 12 is provided with the threaded bore 18 longitudinally disposed and coextensive the length thereof and embodies a laterally disposed offset 19 having a recess 20 which intersects and communicates with aforementioned bore 18, the latter being reentrant, that is, extends downwardly and inwardly into the body of the clamp and clutch support 12 and terminateswithin proximity of the bottom plane of the base plate 14, defining generally a pocket in which the clutch broadly denoted 21 is yieldingly sustained by the spring 22 interposed between one end thereof and the bottom wall of recess 20.

Clutch 21 is the form of a one piece stud comprising an elongated body having the head portion 23, an intermediate restricted connecting member 24, a shoulder or step defining an enlarged portion 25 and a flange 26 yieldingly supported by spring 22.

' Operatively connected with the longitudinally disposed threaded bore 18 is the clamping element generally designated 27 which embodies an elongated threaded stem or bolt 28 suitably carrying at one end thereof the socket or housing 29 in which preferably a resilient member of rubber or a squeegee 30 is secured, it being understood, that instead of securing a yieldable or soft material in the housing, both the housing and squeegee may be eliminated and the stem 28 may be tightened directly against a brace of the upper sash or if the housing with the squeegee be employed, the latter may be also tightened against the upper sash as in Fig. 5 or against a brace of sash 11, the latter being representative of either a front or rear slideable sash, if

the fastener is mounted on the frame or sash casing as in (Fig. 1). At the other end of the clamping element, the stem is formed with an eye 29' providing means for movingthe squeegee either towards or away from the adjacent frame member as is well understood.

It should be observed that the stem, although threaded comprises a longitudinally disposed flat face 31 which cooperates with the flange or disc 26 of the clutch to prevent retraction of the stem, if the clutch 21 is in its normal or raised position (Figs. 1, 3, and 5) In other words, flange 26 of the clutch, normally by rea son of the action of spring 22 is in a position slightly overhanging bore 18 (see Fig. 3) and provides an abutment or stop for the marginal portion 32 of the flat face of the stem, if the latter is moved, say, counter clockwise looking in the direction from manipulator 29' towards the squeegee or clockwise looking in the direcin.,. 1m he e ee o m n u at h re preventing any further movement of the stem in the same direction.

,If, however, it is desired to move the squeegeeto a clamping position, the stem is manipulated by manually actuating the eye 29' in a clockwise direction, looking in the direction of manipulator or eye 29 towards the squeegee thus causing the marginal portion 31 of the flat face 31' to abut and drive against shoulder 25 and drive flange 26 against the spring 22 and consequently move the stud bodily inwardly against the action of spring 22 until the intermediate restricted portion 24 of the stud is in spatial registry with the stem, whereby the latter may be turned freely incompleting its revolution by virtue of theclearance between the restricted portion of the stud and said stem (see Fig. 4).

On each revolution of the stem during the progression of the squeegee towards the adjacent flat face contacts against the shoulder 25 and drives the stud bodily against the spring, causing the stem to be operatively free of the clutch and sash to be secured, the driving margin 31 of the thereby permitting the stem to continue its movement in the same direction without interference until the clamping squeegee firmly presses and bears against the adjacent brace of an pper or lower. sash, as the case may be, al-

though, during the portion of a revolution that the curved surface of the stem abuts the shoulder, the clutch is maintained depressed, and is not restoredto the normal position, namely, retracted, until "the portion of the curved surface ofthe'stem adjacent the margin '31 clears or is free of shoulder 25. f

Where for example, it is desired to release a frame member after having been locked against the frame casing to prevent movement or rattling, clutch '21 is manually depressed by the operator to the position illustrated in Fig. 4 and against the action of the spring thereby freeing the stem from the automatic action of the clutch and in this relation the stem may be tiirned counter clockwise, looking in the direction from eye 29' towards the squeegee that is in this relation, the squeegee of the stern and the latter moves rearwardly and away from the adjacent brace of the frame previously fastened, thuspermitting the slideable frame members to be adjusted in any position within their casing or, if the socket29 is removably associated with the stem, the former may be detached from the stem and the latter removed from the support 13, it being further noted, however, that with the clutch depressed, the stem may also be moved towards a brace for tightening thereagainst without interference by the clutch.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art and it is of course understood that changes in the form, proportion, and minor details of construction may be resorted to withoutdeparting from the spirit of the invention and scope of the appended claims.

I claim:
